Check the tires, certain brands make more noise than others. Maybe add some more sound deadening insulation?

i have changed them already with best tires at all Pirelli Scorpion and still . just if the pavement was new i noticed it become smooth . but the air sound against the car or i mean the hitting sound on the car also .

It a big SUV, aka brick in the wind. What are you comparing the Jeep to? Did you just purchase this vehicle? Did you come from driving a sedan?

Are you maybe talking about the helicopter sound when you have a window open? If you have a front window open, you need a rear one cracked to allow for the air pressure to not build up in the car making the helicopter noise.

yes it is like helicopter noise. but the windows are all closed . and i have replaced them also from the dealer. but it still this sound .

many many thanks to you for your answers i really appreciate your support here .
